Any good anagrams for pigeon whistle?

A pigeon whistle (known as a geling 鸽铃 or geshao 鸽哨 in China) is a device attached to a pigeon such that it emits a noise whilst flying. They have long been used in Asian countries, particularly China for entertainment, tracking and to deter attack by birds of prey. The practice was once common but is now much less widespread owing to increasing urbanisation and regulation of pigeon keeping. A modern version of the device, based on specimens held at the Pitt Rivers Museum in Oxford, has been developed by musician Nathaniel Mann. Mann has performed with the devices attached to racing pigeons at festivals across the United Kingdom.
